| Subject: | FYI December 2014 issue IFR flying |
Because it is winter, there is a good article on Ice and tail stalls in the
referenced issue. I don't fly ice anymore but should you encounter it flying
the 10, the article provides some does and don'ts. Having flown a Cessna
Cardinal for about 30 years and built a Glastar in addition to a 10, I have
learned a little about tail stalls. I first heard of the problem and
considered it back when the C177 did not have the slots in the tail. Pilots
were trying to land the Cardinal and in the flare with flaps deployed, they
stalled the horizontal stabilator. The result was a rapid pitch downward and
a damaged nose gear. This problem can also be demonstrated in the Glastar.
It can be built improperly with the wrong horizontal stabilizer angle of
incidence and a tail stall can be experienced in the flare even without
flaps deployed. Mine was built properly but the pilot who made first flight
in my Glastar made the approach at 10-20 knots faster than normally required
and no flaps to protect himself from such a potential problem. The
referenced article also notes that tail stalls can also be experienced with
flaps deployed and ice on the tail. The problem exists both for high and low
wing aircraft. My plans are to stay out of ice but should I encounter and
experience a tail stall I plan to be prepared.
